SYSTEM FOR A MINIMALLY-INVASIVE, OPERATIVE GASTROINTESTINAL TREATMENT

摘要

Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a first lumen, a first flexible tube positioned in the first lumen, and a second flexible tube positioned in the first lumen. The first lumen defines a first space configured and dimensioned to receive an endoscope. The first flexible tube and second flexible tube are fixed at a proximal portion and configured to float within the first lumen of the catheter. First and second flexible guides are slidably positioned within the first and second flexible tubes and dimensioned to receive a first instrument for axial movement therein, the first and second flexible guides movable to an angled position with respect to a longitudinal axis. A working space expanding system positioned at a distal portion of the flexible catheter, the working space expanding system movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body lumen.

1. A system for performing minimally invasive procedures in a working space within a body lumen of a patient, the system comprising:
a flexible catheter having an inner wall, an outer wall, a first lumen, a first flexible tube positioned in the first lumen, and a second flexible tube positioned in the first lumen, the first lumen defining a first space configured and dimensioned to receive an endoscope, the first flexible tube and second flexible tube fixed at a proximal portion and configured to float within the first lumen of the flexible catheter; a first flexible guide slidably positioned within the first flexible tube, the first flexible guide configured and dimensioned to receive a first instrument for axial movement therein, the first flexible guide having a longitudinal axis and a distal portion movable to an angled position with respect to the longitudinal axis of the first flexible guide; a second flexible guide slidably positioned within the second flexible tube, the second flexible guide configured and dimensioned to receive a second instrument for axial movement therein, the second flexible guide having a longitudinal axis and a distal portion movable to an angled position with respect to the longitudinal axis of the second flexible guide; and a working space expanding system positioned at a distal portion of the flexible catheter, the working space expanding system movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body, the distal portion of the first flexible guide and the distal portion of the second flexible guide movable to angled positions within the expanded region.
